Embodiment 1
[0023] At 35°C, dissolve dehydroabietylamine (DHAA) and cetyltrimethylammonium bromide (CTAB) in deionized water, stir well, then add sodium hydroxide to adjust the pH value, under stirring conditions Add silicon source tetraethyl orthosilicate dropwise, wherein the molar ratio of silicon source tetraethyl orthosilicate, cetyltrimethylammonium bromide, dehydroabietylamine, and sodium hydroxide is 1:0.114:0.00286: 0.5, continue to stir for 2 h, then transfer to a hydrothermal reaction kettle, crystallize at 100°C for 72 h, wash, filter, and dry to obtain silica powder.
Embodiment 2
[0025] It is basically the same as Example 1, except that the molar ratio of the silicon source tetraethyl orthosilicate, cetyltrimethylammonium bromide, dehydroabietylamine, and sodium hydroxide is 1:0.114: 0.00457:0.5.
Embodiment 3
[0027] It is basically the same as Example 1, except that the molar ratio of the silicon source tetraethyl orthosilicate, cetyltrimethylammonium bromide, dehydroabietylamine, and sodium hydroxide is 1:0.114: 0.00714:0.5.
